2 Phase Hybrid Nema 24 Stepper Motor Single Shaft 60AHS140

1. Products Overview

Step motor is an executive agency that converts electrical pulses into corner displacement. You can control the angle displacement by controlling the number of pulses to achieve the purpose of accurate positioning. At the same time, you can control the speed and acceleration of the motor rotation by controlling the pulse frequency to achieve the purpose of the speed regulation.

The hybrid step motor is currently the most widely used step motor, and everyone is familiar with the stepper motor. Here, we briefly introduce how to choose the right step motor for our applications.

How to choose the right step motor for our applications?

The choice of stepping motor torque

The torque of the stepping motor is similar to the "power" of traditional motors. Of course, there is an essential difference. The physical structure of the stepping motor is completely different from AC and DC motors and the output power can be variable.

Generally, we select the motor size according to the torque need in operation. For example, if the torque needed is less than 0.8N.M, frame size 20/28/35/39/42mm stepper motors are suitable. If the required torque is about 1N.M, select 57mm motor. When the required torque is several N.M or even more, usually selected stepping motors with frame size 86/110/130mm or bigger.

The stepping motor speed selection

Special consideration should be taken for the speed of the target stepper motor. Because the output torque of the motor is inversely proportional to the speed. That is to say, when the stepper motor speed is low (500-600 rpm or lower speed per minute), its output torque is larger. When the motor speed is increasing, the motor toque will be decreasing and especially when with the speed of 1000rpm and above.

Sometimes when high-speed motors are needed, the coil resistance, inductance and other indicators of the stepped motor must be considered carefully. Choose a motor with a slightly less inductance is better, as the output torque is normally higher. However, if want low speed and big torque, a stepper motor with inductance no less than 10mH is better.

Selection of no-load-starting frequency

This is a more important indicator for buying motors. If it is required to start and stop frequently within a short time, and the speed is about 1000 rpm (or higher), it is usually necessary to "accelerated startup", i.e need a motor with high no-load-starting frequency.

Phase selection

Regarding to the choice of the number of step motor phases, many customers do not pay enough attention. In fact, the performance of stepper motors with different phases are different. The more phases, the smaller the steps can be done, and the vibration at work is smaller. In most occasions, two-phase motors are enough. However, if higher performances needed, especially for precision or smoothness, 3-phase or 5-phase can be better.

Select the protection level

There are special step motors, such as water-proof and oil-proof, dust-proof for some special occasions. For example, underwater robots, or fountain etc. need waterproof motors.

Kaifull two-phase, three-phase, and five-phase hybrid step motors are made of high-temperature permanent magnet and high-quality cold-rolled steel sheets. Our stepper motors range is very rich, covering 20mm to 150mm in frame size. At the same time, there are all-in-one step motors that integrated with drivers, closed-loop stepper motor, and with brake stepper motor etc..

Generally speaking, the characteristics of step motor are:

Easy drive.

No matter how the input current changes, as long as the load can be driven, the step motor moves according to the minimum angle.

No feedback signal is required. The step motor moves according to the pulse frequency and quantity given by the drive, and does not need to rely on the motor actual status feedback.

The positioning error does not accumulate. The reason why the stepping motor does not accumulates is because it does not need to know the actual location, but only needs to know the number of rotating steps. Therefore, the step motor only needs to receive the signal of each step, and then move according to the step angle. It is not necessary to know the starting location or target location. This can avoid the problem of accumulating errors. In addition, the working principle of the stepper motor makes the movement discrete and performed from a specific angle without a continuous accumulation error.

Stepper motor driver principle is simple and easy to develop control system.

Step motor has the characteristics of high power density, high output torque, low noise, low vibration and smooth rotation, high energy conversion efficiency, stable and reliable, long life etc. At the same time, our company supports the flexible customization, too.
